TDXD in Lung Cancer?

There's a school of thought that lung cancers are more chemo refractory. They're not chemo sensitive and therefore you need a stronger dose. The Destiny Lung O2 had proven that that 5.4 is just as good and less toxic. So I think you do get into like a plateau effect. There is a dose response relationship just like chemotherapy. But because it's through a targeted delivery mechanism, it's not always the more the merrier.
